Final · Friday, September 4, 2026 · Round of 32

Result

Vacherot served twelve aces to six and hit the fastest ball of the match at 140 mph, and none of it mattered: he landed half his first serves, double-faulted seven times, won 41% of the points behind the second, and never broke — nought from three, all three chances in the first set. Tiafoe went at that serve from the start, took the opener 6-4, broke twice more in the second and once again in the third. He won 85% of the points behind his own first serve and made thirteen unforced errors in two hours; Vacherot out-hit him on winners, thirty-four to thirty, and made twenty-seven. It is a seventh consecutive third round in New York for Tiafoe, who has twenty-six career wins at this tournament and reached the semi-finals in 2022 and 2024 — and it is his first fourth round since that 2024 run. For Vacherot it was a US Open main-draw debut: ranked 216th a year ago, the Shanghai champion since, and back from two months out with a stress fracture in his left foot. "They forgot about me a bit," he had told L'Équipe that morning. Tiafoe plays Daniil Medvedev, who beat Vacherot's cousin Arthur Rinderknech earlier in the day.

At this Stage

The Round of 32 is the third round, and the last one before a Grand Slam draw becomes a small tournament: sixteen men's matches across Friday and Saturday leave sixteen players standing, every one of them having won twice on these courts. This is the round where the seeding chart stops doing any work — from here on, whoever is left is who you play.

What I said beforehand

The preview, frozen before the first serve. Clearly dated, never rewritten — that's the deal that makes the pick worth anything.

Tiafoe has been to two US Open semi-finals, in 2022 and 2024, and no player left in this quarter has a longer history of playing well on this particular court in front of this particular crowd. He is 38-17 for the season, 203-166 on hard courts for his career, and eleven days before this tournament began he was in the Cincinnati final. He has also spent a lot of himself already: five sets and nearly four hours against the American Martin Damm on Tuesday night, finishing close to 1 a.m., and then a night session against the qualifier Rei Sakamoto in which he was out-aced 18-7 and out-hit 38 winners to 23 and won in straight sets anyway, on the strength of 18 unforced errors to Sakamoto's 40. Vacherot is playing his first US Open main draw at 27 — remarkable for a man who won the Shanghai Masters last October from qualifying, ranked 204th, the lowest-ranked champion in the history of that level. He beat Kamil Majchrzak in four sets and 3hr 26min on Wednesday with seventeen aces and twelve double faults, which is the range of him. They have never met. The hard-court Elo gap is 97 points, and Tiafoe's tolerance for a loose set is the difference.

The case for Frances Tiafoe

64% to win

Tiafoe is 11th in the world, has reached the semi-finals here twice, and has a career hard-court record more than four times the size of Vacherot's. He was out-served and out-hit by a qualifier on Wednesday and still won in straight sets, because he made 18 unforced errors in three sets and Sakamoto made 40 — which is exactly the profile that punishes a player who hit twelve double faults in his own last match. And this is New York, where only Djokovic and Fritz have more tour-level wins on American soil among active players than Tiafoe's 126.

The case for Valentin Vacherot

36% to win

Vacherot beat Novak Djokovic and won a Masters 1000 title inside a fortnight last October, so the ceiling is not in question — and at 6ft 4in with seventeen aces in his last match he has the serve to shorten points against a man who has already played eight sets this week. Tiafoe needed five to get out of the first round against a player ranked 90th. If Vacherot's first serve behaves the way it did in the fourth set on Wednesday, 74% in and 88% of those points won, this is a very different match from the one the rankings describe.

Both cases written 2026-09-03, before the first ball — frozen into the record exactly as written, whatever the result. The percentages are mine — opinions with a percent sign on. They add to 100 because tennis has no draw to hide the rounding in.

My locked pick: Frances Tiafoe to advance ✓ RIGHT

“Two semi-finals here, 97 points of hard-court Elo, and an opponent who hit twelve double faults on Wednesday.”
